But it's fetching old value from the clip board? but it used to work perfectly fine few days back.
Expected Output is: BCDE"

Basically i got below error first:

But After following below steps error is not coming but clipboard is not saving the copied content during run time: https://stackoverflow.com/questions/8513740/copy-paste-not-working-in-a-signed-applet

On Windows 7, it can be found at C:\Program Files (x86)\Java\jre6\lib\security. Copy this file to your home folder (ex. C:\Users\Kyle). Rename the file to .java.policy (note the period at the beginning). Edit the file in a text editor. Locate this line of text:
Add the following line just below it like so:

// "standard" properies that can be read by anyone
permission java.awt.AWTPermission "accessClipboard";
Save the file. Close any open browsers and ensure that Java is not running before testing.

Console after following above steps:

Not related to Selenium.

May i know which is the right platform? Below statement is the issue, i believe its part of selenium-Robot (import java.awt.*)
String str=(String)Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor);

Error: Exception in thread "main" java.awt.datatransfer.UnsupportedFlavorException: Unicode String
at sun.awt.datatransfer.SunClipboard.getData(Unknown Source)

I mean its copying text and not storing text into clipboard using robot class Key Events, but it used to working fine previously

robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_RIGHT);
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_RIGHT);
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_RIGHT);
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_RIGHT);

Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_RIGHT);
robot.keyRelease(KeyEvent.VK_SHIFT);
Thread.sleep(2000);
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyRelease(KeyEvent.VK_C);
Thread.sleep(2000);
robot.keyPress(KeyEvent.VK_RIGHT);
robot.keyRelease(KeyEvent.VK_RIGHT);

String str=(String)Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor);

If you think there's an issue with selenium, offer a reproducible scenario using only selenium. Otherwise, I'm afraid it's impossible for us to debug. Please raise an issue with the library you are using first. If something "just changed" within the last couple of days, if anything it is probably a driver issue and not a selenium issue.

Java AWT Robot is a part of Java SDK, it's not a part of Selenium.
